- The X-ray spectrometer ‘CLASS’ on the Chandrayaan-2 Orbiter has mapped an abundance of sodium on the moon for the first time.
- CLASS stands for Chandrayaan-2 Large Area Soft X-ray Spectrometer.
- These sodium atoms can be nudged out of the surface by solar wind or ultraviolet radiation more easily than if they were part of the lunar minerals.
- Chandrayaan-1 X-ray Fluorescence Spectrometer (C1XS) detected sodium from its characteristic line in X-rays.
